Using this liquid foundation is easy. First, clean and moisturize your face. Then, take a small amount of the foundation and apply it evenly on your face with a makeup brush or sponge. You can add more if you need better coverage. Remember to close the bottle tightly after use to prevent it from drying out. Keep it in a cool and dry place. Avoid exposing it to direct sunlight. If you have sensitive skin, it's a good idea to do a patch test on your wrist before full - face application.
